Don't use the negation operator frequently

Description

This rule flags code that uses the negation operator frequently (i.e., more than two times).

The negation operator (!) decreases the readability of the program.

Example

 package OPT;
 
 public class DUN {
     boolean method (boolean a, boolean b) {
         if (!a)
             return !a;
         else
             return !b;
     }
 }

Repair

Do not use the negation operator if possible.
